It works great on a L shape elbow pvc joint in my sprinkler box (about 80psi).
There is a very small leak in my sprinkler box, found last fall and confirmed this spring when turn back on the water (photo 2), there a few hair size water shoots out from it. I removed the component and brings to Home Depot, but they said the manufacture is no longer making it (or out of business), and they do not have any replacement in similar size.
So for me, try some alternative solution is the only way to do before spend hundreds to hire professional. I decide to give this a try to this patty before really hire someone to do it, and thanks to many other reviews in this post, even a lot of people says it doesn't work with pressured pipe, I did see there are people successfully make it works.
Based on all other people's experience, I did the following steps with extra caution:
1. clean up all the dirt and debris, wipe out clean with paper towel.
2. rough the surface a little bit with a wood sandpaper (barely add some scratch on the surface, to improve the bond between this patty and the pipe).
3. discards the first1 inch of patty on the edge (some people recommend so), then take a about 1 inch of patty for first application. knead it to bar/snake shape and fold it, repeat for dozens of times.
4. after it fully mixed and soft like peanut butter, make it like bar/snake, wrap it around the leaked position (like a ring over your finger), push it to the surface and smooth the edge (like a band aid around
the ring over your finger).
5. wait 1 hour to 2 hour for first application to harden a bit (the first application only becomes slightly harden after an hour), then do the 2nd application same way to "patch" the 1st application (use 1st application to seal the leak, 2nd application to seal any potential leak of 1st application).
6. wait 3 days instead of just 1 day to let it fully cured (assume there are moisture in the pipe and it take longer to dry)
So far it works well after turning water back on and no more leanings.
I will keep monitoring my pipe, in case if it leaked again, I will update here.
note1: the product i received says its strength is 4370 psi (picture 1), which is much higher than the label in old picture and another product in home depot. I guess that extra strength may also helps if the product is fully cured.
note 2: if your hole is larger, you may need more putty to add extra strength than how much i uses. but i still recommend multiple applications than use everything in one shot.

patched another garden hose with 2 steps. it works for a week but leaks soon after a few usage, i guess flexible pipe may need more skill & patient.
